To tweak or not to tweak

[sw33t]

hi
i am wanting to get the most out of my connection,comcast 6mb/768 or 786kbps i forgot the upload stream but its on of those.

ok i max out my upstream no problems ,usually 90KB/s...is there anything i can do to get more ?
and sometimes my download speeds are lagging but it could be the peers,here is the results of the analyzer: and thanks

TCP options string = 020405b401010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which equals MSS.
Default Receive Window (RWIN) = 65535
RWIN Scaling (RFC1323) = 0 bits
Unscaled Receive Window = 65535

Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)
bandwidth * delay product (Note this is not a speed test):

Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms
MTU Discovery (RFC1191) = ON
Time to live left = 117 hops

TTL value is ok.
Timestamps (RFC1323) = OFF
Selective Acknowledgements (RFC2018) = ON
IP type of service field (RFC1349) = 00000000

I'd download the TCP Optimizer (http://www.speedguide.net/downloads.php), set it to "Cable Modem", choose your Network Card, "Optimal Settings", then "Apply Settings" and reboot :)

Alternatively, you could read some of the tweaking articles for your OS, then apply some tweaks manually. Seems you have already done some tweaking (your RWIN is larger than the default in Windows), or you're running Linux.

Since you're on a 6Mbit line, you'll see the most improvement by increasing the RWIN value to 256960 (and enabling Tcp1323Opts for it to work).

I hope this helps

thank you Philip
i will run the tcp optimizer,and set it as above.

edit:
and yes i also run suse sometimes mostly xp pro sp2 on this comp .
